Traditionally, there was vital scientific debate over the significance of penis measurement. But no consensus has been reached. Lots of our ideas on penis measurement might or is probably not grounded inside actuality. To raised discern reality and fiction, we have now researched the scientific literature.

By and enormous, the dominant perception of each female and male professionals (intercourse therapists, physicians, and psychologists) is that penis measurement is  biologically insignificant. Of larger social relevance, nevertheless, is the connection between measurement and vanity. The aim of the Male Genitalia Package is to assist males really feel higher about themselves by exploring the big variety of “normal” after which discussing the anatomy and physiology of the male genitalia. Use the button to your left to transfer ahead to the Anatomy part. Penises are available all shapes, sizes, colours, and even textures. They’ve been the item of a lot scrutiny by science, the media, and artists, although the precise cause they tackle such a symbolic and central position is unclear.

This website is split into various sections. To get probably the most from this website, we advocate you start with the Introduction part and proceed down the record so as. You’ll be able to transfer from part to part by clicking on the subjects within the left body.

The male genitalia consists each of the exterior genitalia (outdoors of the physique) and the interior genitalia (inside the physique). The exterior genitalia include the penis, scrotum, and pubic hair. The inner genitalia, however, include a lot of hidden glands and tubes that play a task within the manufacturing and supply of sperm.


These embrace the epididymis (e), vas deferens (vas), and prostate gland (pr). Different inner buildings seen within the drawing to the left are the pubic bone (PU), the urethra (u), and the testicle (T). For the sake of brevity, we’ll principally concentrate on the exterior genitalia.

The most blatant facet of the exterior male genitalia is the penis. The penis consists of a physique (shaft) and glans (head). Beneath the pores and skin (as proven within the image of a dissected penis to the suitable) the physique (B) or shaft of the penis incorporates three columns of tissue that may fill with blood to turn into an erection. The corpus cavernosum makes up the majority of the penis tissue. On the underside of the penis is the corpus spongiosum (S) that can also fill with blood to type an erection. Operating down the middle of the corpus spongiosum is the urethra. The urethra is the tube which connects the bladder to the tip of the penis and is the place each urine and semen exit. The penis is firmly hooked up to the pelvic bone by two robust bands of fibrous tissue, referred to as the basis. The root is just not seen besides when dissected. On this image of a dissected penis (wanting on the underside), the pores and skin has been eliminated displaying a number of the underlying buildings. The roots (R) be a part of to develop into the physique (B).

The tip, or head, of the penis is known as the glans (G). It is likely one of the most delicate areas on a person’s physique due to the heavy focus of nerve fibers. Until circumcised, the glans is roofed by a unfastened, hoodlike fold of pores and skin referred to as the foreskin (f) or prepuce. This foreskin might be pulled again exposing the glans. For these circumcised, the foreskin has been surgically eliminated slightly below the glans. There’s typically a wrinkle-like scar on the shaft on the website the place the foreskin was eliminated.

Circumcision is a controversial process whereby the pores and skin usually overlaying the top of the penis is eliminated. It’s generally finished for spiritual or cultural causes and a circumcised penis was believed to be medically superior prior to now. Current medical research have proven that though circumcised males do have a barely decrease fee of penile most cancers and bladder infections compared to uncircumcised males, the distinction is insignificant. At present, a lot of the American medical group believes circumcision to be pointless at greatest, and merciless and disfiguring at worst.

A circumcised and uncircumcised penis. A cross-section via the shaft.

The vertical slit on the tip of the glans is the urethral meatus (m); it’s the opening of the urethra (u). The urethra is a tube-like construction via which each urine and semen stream.


The base of the glans is a coned form referred to as the corona. Across the corona are quite a few small sebaceous glands, which in latin are referred to as glandula Tysonii odorifera. These glands secrete a whitish materials which has a peculiar odor; this cheese-like substance known as smegma.

The scrotum is a unfastened, wrinkled pouch that has two compartments, every of which incorporates a testicle. The testicles are oval, rubbery buildings which might be about four.5 cm lengthy (vary is often three.5 to 5.5 cm). The left testicle often lies considerably decrease than the appropriate. On the again aspect of every testicle is the softer, comma-shaped, epididymis (e); it feels considerably like a bag of worms. Sperm leaving the testicle (the place it’s made), flows by way of the epididymis (e) into the vas deferens (vas), and joins the urethra (u) within the prostate (pr).


The first signal of puberty (often round 9 1/2 to 13 half years previous) is a rise within the measurement of the testicles. Subsequent, pubic hair seems and the penis begins to develop. The full change type preadolescent to grownup takes between 2 and 5 years. The whole course of was studied by Dr. Tanner. His Intercourse Maturity Score is utilized by the medical career to decide what degree of genital improvement has taken place.

Stage 1 is the preadolescent stage. There isn’t any pubic hair (apart from a positive peach fuzz comparable to that on the stomach and elsewhere) and the penis and testicles are in the identical proportions as in childhood.


Stage 2

Stage three

Stage four

Stage 5

In Stage 2, there’s sparse progress of lengthy, barely darkened, pubic hair on the base of the penis. The testicles start to get bigger, and the scrotum begins to get a reddened and altered texture. The penis might develop barely or by no means.

In Stage three, the pubic hair turns into darker, coarser, and curlier and begins to unfold over the pubic bone (PU). The testicles proceed to enlarge and the scrotum texture turns into extra like that of an grownup. The penis lengthens.

In Stage four, the pubic hair grows to cowl the bottom of the penis and begins to grown on the higher a part of the scrotum. The hair will get darker, coarser, and curlier. The scrotal pores and skin will get darker because the testicles continues to develop. The penis continues to develop longer, and will get wider. The glans, or head, of the penis turns into rather more outstanding.

In Stage 5, the pubic hair has unfold to the within of the thighs. The scrotum, testicles, and penis develop to their last grownup measurement and form.


To realize an erection, blood vessels on the entrance of the penis open up and permit blood to move in. The blood (heat and subsequently purple, within the heat-sensitive photograph) then enters the sponge-like tissue of the corpus cavernosum and corpus spongiosum. Because the blood fills into the penis, an erection varieties. Erections are caused by way of the parasympathetic nervous system when the penis and different erogenous zones are stimulated. As well as, sure sights, sounds, smells, ideas and goals (both day-dreams or night-time goals) can set off the blood vessels to open and an erection to type. From early childhood onwards, erections happen throughout sleep. This phenomenon, referred to as nocturnal penile tumescence, happens throughout REM sleep (Speedy Eye Motion) and often happens for about 100 minutes an evening. Having an erection upon wakening within the morning is an instance of this phenomenon.

With persevering with stimulation, an orgasm can happen. The orgasmic expulsion of semen from the penis (ejaculation) is a reflex and never physiologically dissimilar to a “doctor checks your knee” sort of reflex. Whereas an erection could be interrupted at any second by will (or from worry), the ejaculation reflex, as soon as began it can’t be stopped. As soon as triggered, the reflex begins with the motion of sperm from the epididymis (e) (the place sperm is saved after being made within the testicle) to the vas deferens (vas). The sperm strikes into the prostate (pr), and mixes with secretions from the prostate and seminal vesicles and is then expelled by means of the urethra. In wholesome adults, about three cc of semen (containing 300 million sperm) are launched with every ejaculation.

Congenital issues with the male genitalia are prompted throughout fetal improvement.

A surgical incision or circumcision is the remedy of selection for phimosis. Congenital anomalies of the testicle additionally happen sometimes. An undescended testicle (cryptorchidism) is the most typical delivery defect affecting up to zero.eight% of new child males (1 out of each 125) . If the testicle has not descended into the scrotum by 1 yr of age, it wants to be surgically lowered (or eliminated), as numerous undescended testicles will turn into cancerous.

Many condoms come lubricated and/or premedicated with spermicide (a chemical that kills sperm cells on contact). Different condoms product of lamb intestines are costlier and should not shield as properly towards sexually transmitted illnesses. Condoms are designed to hold semen from stepping into the lady’s vagina. To maximise the protecting advantages of condoms, they have to be used appropriately.

Condoms often come rolled up in a package deal. It can unroll to about 7 1/2 inches, although one shouldn’t unroll it till placing it on the erection.

Due to this, solely abstinence is totally efficient at stopping STDs.

To make use of a condom appropriately, pinch the top (the nipple) to get the air out prior to putting it on the top of the penis. This pinched-off area might be the place the ejaculate collects and minimizes the danger of bursting the condom. Roll the condom down the shaft of the erection, masking as a lot pores and skin as potential (many STDs can unfold from pores and skin to pores and skin contact even when there are not any open sores or rashes current). The condom have to be unrolled onto the erection earlier than any intercourse happens as it’s common to leak a small quantity of semen from the stimulated penis prior to ejaculation. In case you are not utilizing a lubricated condom, you must put Okay-Y Jelly or a spermicide onto the condom as soon as it has been positioned on the erection to lubricate and therefore reduce the danger of tearing the condom throughout sexual relations. NEVER use Vaseline (petroleum jelly) on the condom as it could actually dissolve the latex. When withdrawing the condom-covered penis from the vagina or mouth, be certain to maintain the rim to forestall it from slipping off and spilling sperm onto mucous membranes. In case of an unintentional spill round or within the vagina, insert spermicide cream, jelly, or foam gently in and across the vagina. Don’t douche.

Mark the spot the place the string first touches itself. three. If utilizing string, take the marked string and lay it towards the ruler. Learn to the closest quarter-inch measurement. four. Report this quantity within the area offered on the calculation sheet or in your paper 5. Repeat this measurement two extra occasions, ideally with totally different erections and ideally on totally different days as penis measurement will differ relying on the extent of arousal, time of day, room temperature, and recency of sexual exercise. (The research from which these knowledge have been obtained didn’t standardize these variables.)


One other means to decide how your penis compares to all the male inhabitants is to use a pie-chart. To find out your “slice of the pie”, discover your erect penis size on the pie-chart. The measurement of your pie-chart slice represents what phase of the inhabitants has the identical erection measurement as you. The the rest that’s discovered counter-clockwise to your slice to the 12 o’clock place represents the portion of the inhabitants that has a shorter penis. The portion of pie discovered clockwise to your slice has an extended penis. For instance, in case your erection is 6 1/four (e.g., 6.25 inches), then 9.eight% of the inhabitants additionally has a 6.25 inch erection. Wanting counterclockwise, 48.eight% of the inhabitants has an erection that’s lower than 6.25 inches (e.g., 24.four + 5.three + eight.1 + three.four + 7.6 = 48.eight). Wanting clockwise, 41.2% of the inhabitants has an erection that’s longer than 6.25 inches (e.g., 15.6 + + + 9.6 = 41.2).

Information & Fiction Solutions

1. Ladies favor males to have an enormous penis. False

A 1983 research (Fisher et al.) requested 154 lady undergraduate college students to learn quite a lot of erotic passages which differed solely within the measurement of the male penis within the story. The ladies have been then requested a normal set of questions to decide their degree of arousal. The research discovered that, normally, penis measurement was an unimportant issue within the degree of arousal of those ladies. A survey of girls by the Diagram Group in 1981 confirmed that when requested to what a part of a person’s physique do lady pay most consideration, 39% stated the buttocks. Solely 2% of girls indicated an curiosity within the penis. Different research (e.g., Masters and Johnson, Hite, Wolfe) have proven that penis measurement has little or no to do with both a lady’s stimulation throughout intercourse, or the chance that she is going to attain an orgasm. In abstract, the literature studies that the overwhelming majority of girls don’t care if a person has a small, medium, or giant penis.(the latter half is extra essential than the previous)

2. Regular erect penises ought to level straight. False

Tabulation and evaluation of the Kinsey Knowledge (Gebhard, et al.) confirmed that roughly 50% of penises do certainly level straight. The remaining 50% pointed in quite a lot of instructions. They discovered that 30% pointed straight up, 10% pointed to the left, 6% pointed down, three% pointed to the fitting, and the opposite 1% pointed in some mixture of those instructions (i.e., up and left). (This knowledge didn’t adequately describe curved penises, specifically people who begin out pointing straight then curve off in one other course.) three. An enormous penis when unerect, will probably be an enormous penis when erect. False A 1988 research (Jamison et al.) seemed on the change in measurement when going from an unerect (flaccid) state to an erect state. The research in contrast two teams of males, these with smaller flaccid penises and people with greater flaccid penises. Though they discovered comparatively giant variations in flaccid penis measurement between males when  erect, the variations disappeared. In different phrases, smaller flaccid penises develop considerably greater than bigger flaccid penises such that when erect each penis teams are primarily the identical measurement. A Masters and Johnson research (1966) additionally described this phenomenon. Put one other approach, the quantity (size X circumference) of everyone’s penis is analogous; longer penises are thinner, shorter penises are fatter. four. Tall males have greater penises than brief males. False A 1993 research (Siminoski et al.) analyzed the connection between penis measurement, physique measurement, and foot measurement, based mostly on the folklore that tall, big-footed males had huge penises. 63 virile males (aged 27-71 years) have been measured. The research discovered that though tall peak and enormous shoe-size have been weakly correlated to bigger penises, variations have been minimal and statistically insignificant. 5. African People have greater penises than Caucasians. True As a gaggle, African People do have barely longer and thicker penis than their Caucasian counterparts. That is proven on these graphs.
